IPC: G11B5/008
Filed: 1993-06-30
Abstract: PURPOSE:To reduce the power consumption of an IC, to make a HiFi recording amplifier circuit and a video recording amplifier circuit one chip, to realize the automation of the adjustment, etc., of a recording current and to load it on a rotary cylinder by providing an external transistor and a DC feedback circuit. CONSTITUTION:A collector of the transistor Q1 is connected to the output terminal OUT of the recording amplifier circuit 1, and is connected to the bias terminal B1 of the recording amplifier circuit 1 through a DC feedback type amplifier circuit A2. The base of the external transistor QX whose emitter is connected to a current Vcc is connected to the bias terminal BI. By the DC feedback type amplifier circuit A2, the DC potential of the output terminal OUT of the recording amplifier circuit is detected, and the collector current of the external transistor QX is adjusted by DC feedback so as to become the required potential. Thus, no DC component flows through a magnetic head HD by a capacitor C1, and the power consumption of the IC is reduced.

Title: Cargo handling machine operation method
Inventor: SAKURAI TAKESHI
IPC: B65G67/60
Filed: 1981-10-12
Abstract: PURPOSE:In loading and unloading by a glove bucket between vessels and the shore, to  automatically perform a cargo-handling work safely by finding an out of contact point  among a transversing start line, a vessel hatch and the bucket, and the time when  winding-up and transversing are simultaneously performed to operate a cargo handling machine. CONSTITUTION:In a mechanism for grasping a bulk cargo 6 in a hatch 5 by a glove  bucket 3, winding up the bucket by a trolley traversing on a traversing beam 1, and  loading a hopper 8 of a quay 7 by traversing movement of the trolley 2, a distance l  is determined in such a manner that the bucket may not strike on a rock-falling preventing plate 11 on land even if winding-up of the bucket 3 is stopped while the winding-up and land traversing are simultaneously operated, a start point is found in such  a manner that when the bucket reaches the safe traversing speed level I, the traversing speed of the trolley is not avove the velocity Va within the range of 10% at minimum  to 100% at maximum, so as to fix a starting start line L-1, and when winding-up  amounts above a setpoint in the line L-1, the land traversing operation is started. Thus,  an automatic cargo-handling can be accomplished with high efficiency, and the bucket  is prevented from striking on the rock-falling preventing plate even if winding-up is  stopped while winding-up and traversing are simultaneously operated.

Filed: 1992-06-22
Abstract: PURPOSE:To regularly clean a magnetic head without affecting an intermittent recording by slightly rotating a loading gear in an unloading direction while the intermittent recording is carried out. CONSTITUTION:The magnetic head is cleaned by a cylindrical member 4 and made to a recording state by excuting a loading operation for winding a magnetic tape on both cylinders 1 and 2 and then, the intermittent recording is executed from this condition and made to a recording state for a long time.

Patent JP-S5588485-A (JP)
Title: Reduction method for amplitude fluctuating noise
Inventor: CHIBA MITSUO
IPC: G11B5/027
Filed: 1978-12-26
Abstract: PURPOSE: To reduce the amplitude fluctuating noise by mixing the amplitude modulation signal to  be recorded with the signal with the carrier given the 90°-phase turn, detecting the amplitude  fluctuating component at the reproducing time and then giving the amplitude modulation to the  reproduction output signal with its adverse phase.   
     CONSTITUTION: In case the video signal is recorded, the phase inversion is given with every hour to the carrier output of the synchronous detection to be added with the carrier output. This output  signal receives the carrier reduction amplitude modulation to secure the balanced state at the  silence time. Then the carrier featuring the fixed amplitude with the 90°-phase shift is applied to  the output along with compounding to the luminance signal for recording on the magnetic tape.  In the case of the reproduction processing, the synchronous detection is given to the pilot signal  which received the frequency conversion through synchronous detector 59 in order to deliver the  amplitude fluctuating noise. Using this output as the control signal, the reduction is given to the  amplitude fluctuating noise through variable gain amplifier 61. This output in then supplied to the  comb-line filter consisting of 1H-dealy line 63, subtractor 64 and adder 65 each, and thus two  color signals received the balanced modulation are obtained with frequency separation from subtractor 64 and adder 65 each.

IPC: F04C2/18
Filed: 1980-11-19
Abstract: PURPOSE: To make applicable to power steering and promote its durability by preventing wear and tear of sealing surface by making an initial clearance between a gear and a sealing block to keep them untouched at all times.  
     CONSTITUTION: Although a sealing block 19 is given an impetus by a coil spring 20, a stroke end of the sealing block 19 is determined by the relation between divisions 24 and 25. As the result an initial clerance c is made between a sealing surface 19a of the sealing block 19 and a tooth crest of gears 14 and 15 as shown in the diagram. In other works even when the sealing block 19 is closest to the gears 14 and 15, the clearance c is maintained to keep them untouched at all times. By this way, wear and tear of the sealing block 19 and generation of shaving powder and an accident such as clogging due to shaving powder getting into a power steering control valve, etc. can be avoided.
